RE50/B

Omnidirectional Dynamic

Microphone

General Description:

The Electro-Voice® RE50/B is specially shock-isolated,
omnidirectional, dynamic microphone created for the
most exacting professional applications. An advancement
in shock-mounting techniques, it was designed
particularly for handheld broadcast and sound­reinforcement use. All handling noise, clothing noise, and
even cord shock have been isolated from the microphone
element so that mechanically induced noise is greatly
reduced. By use of a high-mass zinc internal acoustic
chamber, shock mounted within the machined-aluminum
outercasing, the RE50/B offers a degree of isolation
unprecedented in omnidirectional dynamic microphones.
The internal transducer uses a mechanical nesting
concept all its own. Each part is nested inside another so
that the transducer (head assembly) is nearly a solid
structure. It is highly resistant to damage from shock.
The diaphragm is unaffected by temperature extremes
and atmospheric conditions. A carefully designed integral
windscreen and blast filter provides excellent protection
from wind noise, excessive sibilance and annoying “P­popping.” The RE50/B has a grille that bounces back to
retain its shape. A four-stage pop filter prevents dust and
magnetic particles from reaching the diaphragm. The
RE50/B’s attractive, nonreflecting, semi-gloss black finish
is ideal for on-camera use.

Architects’ and Engineers’ Specifications:

The microphone shall be an omnidirectional, dynamic type with broadcast range response from 80-13,000 Hz. It shall
employ a high-mass zinc acoustic chamber, integral with the head assembly that shall be shock isolated within an
external aluminum case. It shall have a four-stage pop filter to prevent dust and magnetic particles from reaching the
diaphragm. Nominal impedance shall be 150 ohms (such that it will match 50-150, and 250-ohms inputs). The line shall be
balanced to ground and phased. Output level shall be 1.8mV/pascal. The magnetic circuit shall be a nonwelded circuit and
employ Alnico V and magnetic iron. The inner case shall be made of zinc and the outer case of machined aluminum. The
microphone shall have a maximum diameter of 49 mm (1.94 in.) and a length of 197 mm (7.75 in.). Shank diameter shall
be 25 mm (1.0 in.). Weight shall be 269 grams (9.5 oz.). Finish shall be semi-gloss black. The microphone shall have a
built-in connector similar or equivalent to the Switchcraft A3M. The Electro-V oice RE50/B is specified.
